Speex for TI MSP430 microcontroller - estimating CPU speed requirements?
Interested in building a speex codec (basically audio <-> speex <-> data stream) using TI's small MSP430 microcontroller. Is there any way to estimate feasibility based on CPU requirements? Example - speex is happily encoding on an old Pentium-1 processor (166 MHz) using about half the CPU (as reported under Linux); the TI microcontrollers are much slower yet (8-16-25 MHz) and

Speex WBB decoder on AT91SAM7S microcontroller?
Hi, I would like to compile the Speex fixed-point, WB decoder for an AT91SAM7S256 ARM7 microcontroller using gcc-arm-elf and was wondering, before I roll up my sleeves and try to figure out all the autoconf things that I'm really unfamiliar with, if anyone else has done this and can share their experiences. I see in the archives that some folk have compiled for this processor before but

CodeWarrior for Microcontrollers under Wine, can't install
Hello, I'm trying to install CodeWarrior for Microcontrollers, an IDE used for development of embedded systems using microcontrollers from Freescale. (the Special Edition is available freely from their web page) The install begins correctly, however it aborts suddenly. Terminal output is: (7) [renan at amaranth:~] $ wine /media/Renan/CW_MCU_V6_2_SE_11262008.exe

[LLVMdev] New to LLVM, Help needed
Hi, I have started to write an llvm backend for one of our microcontrollers (PICxx). I started studying the framework of PowerPc backend of llvm and decided to start by following that framework. Now I have most of the classes and Tblgen files written for a very basic hypothetical microcontroller with very few instructions. The project builds and the llc recognizes the new processor, however,

Has anybody tried to program MSP430 microcontrollers from TI?
Hi all, I'm rappedly moving away from windows, but one of the last programs i need to run in windows is 'IAR Embedded Workbench (Kickstart Version)' I've tried to run it some time ago (i think about 2 months back) in wine, but it didn't work so well back then. I haven't tried it with newer versions since then. I need that program so i can program my msp430

Speex WBB decoder on AT91SAM7S microcontroller?
Stripping out usused stuff is very easy, especially with static libraries. The only thing that could cause problem is the speed of the CPU. It's very hard to say what the requirements are because it depends a lot on the exact CPU you're using and (for ARM) the configuration of the cache and the speed of the bus.

Speex in a PocketPc crashes sometimes.
Hello Cesar I'm using Speex on a PPC2002 and PPC2003 with no problems. For tune-up remember to define the FIXED_POINT macro in Project->Settings in eVC. With this setting you ought to be able to at least decode in realtime while using debug-mode. Kind regards Bjoern D.

Using opus on ATMEL 32-bit RISC microcontroller
Hi Daniele, On 26/08/16 10:39 AM, Daniele Barzotti wrote: > Have I any way to reduce the source footprint? > (Eg. throw away unecessary files, if there are any..) Well, the first question is whether you want encoding, decoding, or both. If there's one you don't need then you can remove that (unfortunately, there's no easy way right now). Even if you need both, then you can

Using opus on ATMEL 32-bit RISC microcontroller
Hi all, thanks a lot for your replies! Sorry for my typo, the flash size is 8MB (Byte) :-) Unfortunately I cannot use another flash because I'm working on a proprietary board. Jean-Marc, thanks for your suggestions. I thought to use fixed point for convenience, but I can work on floating point too, so I will take in account the codec2 (I didn't know it). Moreover, if you all have

Using opus on ATMEL 32-bit RISC microcontroller
Hi, First of all, I'm quite new to opus. I'm trying to use fixed point opus on an ATMEL AT32UC3B0512. I added the opus source into mine sw tree, I trim off code I don't use (eg. arm, x86 folders) It compiles, but the generated image is too big to fit in the flash. Have I any way to reduce the source footprint? (Eg. throw away unecessary files, if there are any..) Thanks, Daniele.

Ogg files versus Ogg streams
Hi all, I'm very new to Ogg, and am learning about it in an attempt to stream it from a CF card through a microcontroller. This particular setup requires me to move parts of the file from the CF card to the microcontroller buffer, effectively making the file like a data stream. Also, should this question be directed at the Tremor group instead since that is the codec I'm using? It
